# Privacy Policy
**Effective Date:** May 31, 2026
This privacy policy governs your use of the mobile application **Duplex PDF Splitter** (hereinafter referred to as the "App"), created by the developer.
The App is designed to split a single PDF file into two separate PDF files: one containing all odd pages and one containing all even pages.

## 1. Information Collection and Use
### 1.1 Document Privacy (PDF Processing)
- **Local Processing Only:** The App processes all PDF files entirely offline and locally on your device.
- **No Uploads:** Your PDF documents, text, images, or metadata are **NEVER** uploaded to any remote server, cloud storage, or database. All processing takes place within your device's web runtime environment.
- **Temporary Storage:** The App temporarily writes the split PDF documents to your device's cache folder for the sole purpose of enabling you to download or share the files. These cache files can be cleared by your device's operating system at any time.
### 1.2 Personal Information
We do **not** collect, store, transmit, or share any personally identifiable information (such as your name, email address, phone number, location, or contacts).

## 2. Third-Party Services & Advertising
To support the free availability of this App, we integrate advertising services provided by a third-party vendor.
### 2.1 Google AdMob
The App uses Google AdMob to display advertisements (banners and interstitial ads). Google AdMob may collect and process device-specific information, including:
- Your device's advertising identifier (e.g., Google Advertising ID or GAID).
- IP Address (which may be used to estimate general location).
- App interaction and performance diagnostics data.
This data is collected directly by Google AdMob and is governed by Google’s own privacy policy. You can review how Google manages ad data here:

## 3. App Permissions
To perform its functions, the App may request the following permissions on your device:
- **Internet Access:** Required to load advertisements from Google AdMob and fetch CDN-based helper libraries.
- **Storage/Filesystem Access (Cache):** Required to write the generated PDF files to temporary cache storage so they can be exported to your device.
- **Share/System Dialogs:** Required to trigger Android's native share sheet, allowing you to save the files to your device or send them to other apps.

## 4. Children’s Privacy
Our App does not collect any personal information from children. If you are a parent or guardian and you are aware that Google AdMob has collected information on a device used by a child, please review Google AdMob's policies regarding children's advertising settings.
